6 Adjustment and Calibration
6.1 Overview
Adjustment and calibration are an important part of the installation procedure, and
may also be required following maintenance and repair work. The purpose of
adjustment and calibration is to ensure that all pipetting channels are using the
same set of coordinates and moving in the same space. It guarantees the best
performance for tip pick-up and pipetting in very small wells.
Whenever a Pipetting Arm, Pipetting Channel, Pipetting Head, Autoload drive
10
or
the Master PCB is removed or replaced, run the appropriate Adjustment Macro
Program from the Service Software and decide if any corrective action needs to be
undertaken.
After delivery of the instrument, run the check program and only perform an
adjustment if values are out of range.
Adjustment and calibration is also needed when problems occur (e.g. in running an
application, Channel positioning, Tip pick-up and ejection, or when Steps are Lost)
and corrective action is indicated.
After any adjustment and calibration, the functioning of the component concerned
must be verified to ensure a properly working Microlab STAR Instrument.
Attention: before starting any Adjustment and Calibration Work empty and
decontaminate deck panels (e.g. remove all Carriers and Labware from deck)
Conditions:
All Guides in X-, Y- and Z-Direction must be straight i.e. may not be bent and must
ensure a parallel movement to the corresponding axis.
If pipetting heads are replaced, ensure a proper mounting onto channels.
The first three degrees of freedom of the Pipetting Channel must be perfectly
adjusted before running any Adjustment Program. Typically when a Pipetting
Channel is replaced, or when bad adjustment values indicate the requirement of any
corrective actions.
